Disclosed herein is a device in the form of a bung for insulating a container interior from the ambient environment, the bung comprising: a plurality of insulating segments; and one or more barriers for reflecting infrared radiation. Disclosed is: a method of preparing a shipping system for retaining a cryopreserved sample, the method comprising: loading a cryopreserved sample into a container such as a vacuum flask; and fitting the bung to the container to insulate the container interior from the ambient environment, and a method of cooling a container, such as a vacuum flask, for retaining cryopreserved samples to a desired temperature, the method comprising: cooling the container interior by pouring a cryogenic fluid such as liquid nitrogen into the container; and emptying the cryogenic fluid from the container, once the cooling has at least partially taken place.

A refrigerating apparatus applied to a refrigerator is disclosed. The refrigerating apparatus includes a refrigerant, a depressurization gas, an evaporator, a condenser, a first connecting pipe, a second connecting pipe, a third connecting pipe, a blower device and a refrigerator body. The evaporator is provided with an inlet and an outlet; the condenser is provided with a condensation cavity, a gas inlet, a gas outlet and a liquid outlet; a molecular sieve membrane is disposed in the condensation cavity; one end of the first connecting pipe is connected to the outlet and the other end to the gas inlet; one end of the second connecting pipe is connected to the liquid outlet and the other end to the inlet; one end of the third connecting pipe is connected to the gas outlet and the other end to the inlet.

A refrigerator includes a cabinet having a first storage compartment and a second storage compartment, and a cooling module removably mounted to the cabinet. The cooling module includes an evaporator, a condenser, and a compressor. A first cold air duct extends from the first storage compartment and is configured to allow a portion of the cooling module in which the evaporator is arranged, to communicate with the first storage compartment when the cooling module is coupled to the cabinet, and a second cold air duct is different from the first cold air duct and extends from the second storage compartment. The second cold air duct is configured to allow the portion of the cooling module in which the evaporator is arranged, to communicate with the second storage compartment.

A method for monitoring a drawer interior of a vacuum drawer device when the lid is supported by the drawer airtight and closed, includes: periodic measurement of the relative humidity with a humidity sensor arranged in the path of a dehumidifying channel in the lid or, respectively, the drawer interior; comparison of the measured relative humidity with an upper threshold; and as soon as the measured relative humidity is above the upper threshold, opening the valve and inducting a ventilator arranged in a recess or in the path of a dehumidifying channel in the lid. Fresh air is sucked through an air inlet opening, circulated, and thereafter released again from the dehumidifying channel and the drawer interior communicating therewith, until the relative humidity reaches a lower threshold measured by the humidity sensor. Then the valve is closed, the ventilator is stopped, and the controller switches into the humidity monitoring mode.

A temperature-controlled enclosure for displaying cold items. The enclosure includes a body having a front opening and defining an interior space. A frame assembly is coupled in the front opening. One or more doors are coupled to the frame assembly. At least one of the doors includes one or more window panels, a housing assembly that holds the window panels, and a gasket. A ridge projects from the rear surface of the housing assembly between the gasket and the interior space of the enclosure. The ridge extends across a portion of an air gap between the rear surface of the housing assembly and a front surface of the frame assembly.

A refrigerator includes a cabinet configured to have an inner case in which a storage chamber is formed, a cooler configured to cool the storage chamber, a heating device configured to be spaced apart from the cooler and heat the storage chamber, a circulation fan configured to circulate air in the storage chamber, and a controller configured to operate the circulation fan when the heating device is operated.

A refrigerator including a storage compartment, a storage box, and a cover assembly. The cover assembly including a cover member to cover an upper portion of the storage box, a frame provided along the cover member and configured to fix the cover member and comprising an opening provided to communicate with the discharge port to allow cold air to flow into the storage box, a knob configured to be movable and disposed on a side of the frame, a connecting member configured to slide inside the frame and connected to the knob, a guide member configured to be movable inside the frame based on a movement of the knob. The guide member comprising a guide hole, and an opening and closing member configured to open and close the opening by moving in a vertical direction along the guide hole.
